Ideally some proven track record of doing that that you can show people helps. Organize an event, work the phones, meet more people, do some marketing, do some media purchasing, learn finance, learn how to write contracts, learn how to interview/hire/manage... things like that. The more you can prove you've got something valuable to bring to the party, the easier it'll be. Deck is already stacked against you - there's more people with business credentials that want a technical partner than vice-versa, but if you've got legit proven skills it shouldn't be too hard. Build/prove those skills out.
